To me, the sears one was totally worth it for the price (under $200 new). Mounting only takes 10/15 mins. I went one size smaller than the largest one they had. My 2 cents.
Agree. When we bought ours years ago, size was the major decision. We wanted the largest - cheaper model. The install is probably not the easiest to do, but easily doable in 10-15 min. We only use ours maximum 1-2 per year when we go on long vacation, so I am not too worried about spending extra time installing it on top of the cruiser. If I need to install it often, then maybe other models that have easier installation/mounting system may make more sense.
